Dear Greg,
I'm interested to know how good the filters are aligned (the left-eye and the right-eye) regarding the polarisation axis orientation.
I have a cheap polarising sunglasses that have ~3°~5° mis-alignment between the filters. When I put them on I start feeling a sea-sickness coming on me - even on land. I attribute that to the mis-alignment of the filters that eleminates the glare differently to each eye - affecting the binocular/stereoscopic vision, making my brain go dizzy.
Please comment.
Warm regards,
Tony
